I know we went over the mechanism of alkylation of amines in class but could you explain it again? (It is SN2 with amine as a nucleophile: http://ochem.orgfree.com/sn2.html - GS). Could you also explain how alkylation of amines is different from acylation of amines? (Acylation of amines proceeds by the nucleophilic acyl substitution that will be discussed in unit 10. - GS).
